導(dǎo)軌的結(jié)構(gòu)與特長(zhǎng)
The structure and advantages of the guide rail
鋼球沿著LM軌道和LM滑塊上經(jīng)精密研磨加工而成的4列滾動(dòng)面進(jìn)行滾動(dòng)；通過球保持器與組裝在LM滑塊上的回球器，使鋼球列作循環(huán)運(yùn)動(dòng)。
The steel ball rolls along the LM track and LM slider, which are precision ground and processed into four rows of rolling surfaces; By using the ball holder and the ball return device assembled on the LM slider, the steel ball column moves in a circular motion.
為使LM滑塊上的4個(gè)作用方向（徑向反徑向和側(cè)向）均具有相同的額定載荷，各鋼球列被設(shè)計(jì)成按接觸角45°配置，因此無(wú)論何種姿勢(shì)都可以使用。
In order to ensure that the four action directions (radial, anti radial, and lateral) on the LM slider have the same rated load, each steel ball column is designed to be configured with a contact angle of 45 °, so it can be used in any posture.
并且因能施加均等的預(yù)壓，從而既能一邊維持較低的磨擦系數(shù)，又加強(qiáng)了4個(gè)方向的剛性。同時(shí),因斷面高度低,并且對(duì)LM滑塊進(jìn)行了高剛性設(shè)計(jì),從而能獲得穩(wěn)定的高精度直線運(yùn)動(dòng)。
And due to the ability to apply equal preload, it can maintain a lower coefficient of friction on one side and strengthen the rigidity in all four directions. Meanwhile, due to the low cross-sectional height and the high rigidity design of the LM slider, stable and high-precision linear motion can be achieved.
4方向等負(fù)荷
4-direction equal load
為使LM滑塊上的4個(gè)作用方向（徑向反徑向和側(cè)向）均具有相同的額定載荷，各鋼球列被設(shè)計(jì)成按接觸角45°配置，因此無(wú)論何種姿勢(shì)都可以使用,用途廣泛。
In order to ensure that the four action directions (radial, anti radial, and lateral) on the LM slider have the same rated load, each steel ball column is designed to be configured with a contact angle of 45 °, so it can be used in any posture and has a wide range of applications.
低高剛性
Low center of gravity and high rigidity
通過對(duì)LM軌道橫斷面尺寸的小型化，使變低，同時(shí)實(shí)現(xiàn)了高剛性。
By miniaturizing the cross-sectional size of the LM track, the center of gravity is lowered while achieving high rigidity.
自動(dòng)調(diào)心能力
Automatic centering ability
由于THK獨(dú)特的圓弧溝槽的正面組合（DF組合）具有自動(dòng)調(diào)力,即使施加預(yù)壓也能吸收安裝誤差,從而得到高精度平滑穩(wěn)定的直線運(yùn)動(dòng)。
Due to THK's unique circular groove front combination (DF combination) with automatic adjustment ability, it can absorb installation errors even when pre pressing is applied, resulting in high-precision, smooth and stable linear motion.
世界標(biāo)準(zhǔn)尺寸
World standard size
的尺寸設(shè)計(jì)以由直線運(yùn)動(dòng)系統(tǒng)之先驅(qū)THK所開發(fā)的事實(shí)上以成為世界標(biāo)準(zhǔn)的全鋼球LM滾動(dòng)導(dǎo)軌HSR型為基準(zhǔn)。
The size design is based on the fact that the HSR type of all steel ball LM rolling guide rail, developed by THK, a pioneer in linear motion systems, has become a world standard.
